Ukwethulwa kwe-end carbon commutator

Ukusetshenziswa kwezinhlanganisela zekhabhoni nekhabhoni ukwenza ama-DC motor commutators kwafundwa ososayensi baseJalimane ngasekuqaleni kweMpi Yezwe II.
Ngemva kokunqotshwa kweJalimane, ososayensi baseJalimane bathunjwa amasosha ase-US futhi bangena ukuze baqhubeke nocwaningo lwabo.
Kodwa lapho injini ye-brushless iphuma, yathola ukunakwa ngokuphila kwayo okude. Ucwaningo lusebenzaukuqeda abagibeli bekhabhoniibambezelekile isikhathi eside.
After the automobile adopts the EFI device, the fuel pump cannot use the brushless motor due to the limitation of volume. The fuel pump of the EFI automobile is immersed in the fuel to work, and the gasoline currently produced and sold in my country has a relatively low sulfur content. High, copper commutator working surface, in addition to the burning of electric sparks when carbon brushes are commutated, it will also accelerate wear due to chemical corrosion of sulfur. Furthermore, in order to cope with the insufficient supply of fuel in the future fuel market and to control automobile exhaust pollution, the Chinese government has started to sell corrosive ethanol gasoline on a pilot basis. A joint test by the Chinese Academy of Sciences and Tsinghua University shows that the current additives in ethanol gasoline will cause strong corrosion to the metal commutator, resulting in a significant reduction in the service life of the car, and directly lead to various engine failures.

Okwamanje, i-European Union namanye amazwe aseqalile ukwenza amazinga afanele, futhi aseqalile ukukhuthaza nokusebenzisa amaphampu kaphethiloli asebenza ngogesi.ukuqeda abagibeli bekhabhonikuma-cores abo epompo ukuze bathathe indawo yethusi nezinye izihambisi zensimbi ukuze kunwetshwe impilo yesevisi yamaphampu kaphethiloli. Inkathi yokwamukelwa okwandile kaukuqeda abagibeli bekhabhonikumaphampu amafutha ezimoto afikile.
